Ive got a 92 Si org motor 123k on it. Everything is plugged in and oil is full. Tried swapping the solinoid gasket and screen are new. The problem comes in a 3rd gear pull on the highway vtec crossover hits and cel comes on. Any ideas on this problem is appreciated.

 

bump this really bothers me

Did you check to make sure that theres no breaks in the wiring for VTEC? Make sure the connector on the solinoid is connected good and such.

 

i was throwing the same code last night, check all your plugs, check oil level, turns out i had a small leak between the head and the solenoid, did you use hondabond when you put that solenoid on?

 

no hondabond but new gasket/screen. have not checked plugs but would that throw off vtec? Ill check the plugs tommorow. All connections are good as i can tell man nothing looks hacked its a no swap 92 si z6

Well....The only thing I could think of is that maybe your VSS is taking a ****. I dunno....What code are you throwin'?

 

Does this only happen in 3rd gear? Has to be coincidental because a manual ECU doesn't know what gear you're in. Does the CEL just blink on or do you have to physically reset it?

 

yea man as soon as i change to 3rd gear BAM code 22. I have to turn car off and on and code goes away. vss talking ****? i do feel that my spedo could be off at times could this throw the 22 in 3rd?

Bump for someone to help jesus i know this isnt a one off problem

 

Maybe it's just the speed you're going, and not really that fact that you're in 3rd. Try skipping 3rd gear and see what happens.

 

i will try that right now good idea

 

Ummm yes the ecu does know what gear you are in.

I have a chipped P28 and when datalogging it tells me exactly what gear I am in.

I had this same problem. When running a 1/4 I hit third gear and bam, CEL.
Try this because this was also a symptom

Get up to about 55 mph and make sure you are in 5th gear. Now slow down while leaving it in 5th gear. Don't push the clutch in or anything, just slow the car down in gear. Let me know if you get a CEL when you get down to around 10 or so MPH.

I didn't have a single oil leak on my motor. Had a dent in my oil pan and oil pickup tube was a little tweaked but all was decent.
Only other lead I had was that the ignitor coil in the dizzy could cause this.

I ended up selling the motor and never got around to finding the root cause. If I get the same thing on my new motor then I will swap the dizzy out for my GSR one to verify that.

Good luck and let us know if you figure it out.

 

bump the night away

 

i tried the 5th to about 15mph no CEL. did how ever notice at 60mph my mph needle jumped for a split second.

Ok fellas I'm At my ends with this. Ive tried a new solinoid a new VSS and the fluids are full. Its a z6 no swap 92 si hatchback. I keep throwing code 22 in 3rd gear please help.

Well, a Code 22 is a VTEC Pressure Switch problem, not the solenoid. You need to determine if the problem is electrical or mechanical. To check electrical, use a multimeter and check for continuity between the VTEC Pressue Switch wire (Blue with black stripe) and the ECU (Pin D6). Then use a test light or do a continuity check for the Black Wire at the VTEC Pressure Switch to Chasis ground. You need to verify it's got a good ground or you will get a CEL.

If that checks out OK, then the problem could be with the VTEC Pressure Switch itself (not super likely) or their could be debris blocking your oil supply passage. Maybe when you removed your old filter, a piece of rubber or other debris fell into the feed passage. You can remove the solenoid and visually inspect the passage on the head, solenoid housing, and the filter itself. Another option is to pickup a service manual and follow the troubleshooting guide. You can connect an oil pressure sensor to an aux port in the head and watch it when you go into VTEC. This will let you know if you've got enough oil pressure building.

Who knows, it could be something totally un-related. Could be a clogged/damaged oil pickup, clogged oil filter, weak oil pump (not likely). Something is allowing enough oil pressure to build to shut off you low oil idiot light, but not enough pressure to properly supply the engine with the pressure it needs. Being that this just happened after you changed the VTEC Solenoid filter, I'd say none of these are likely the problem.

 

Could be a clogged/damaged oil pickup? The guy i bought it off of did put a new oil pan on the car. how easy is it to replace one?
